Feature

Telemetry

Starting with this release (v34.2.2), Syncfusion® ASP.NET MVC controls introduce telemetry (development-only) to help us better understand product usage, feature adoption, usage trends, and make informed product roadmap decisions.

Telemetry is enabled by default in development environments and collects only anonymous usage information. It is automatically disabled in production environments, and no telemetry is collected from deployed applications or end users.

Telemetry-supported Components:
Telemetry is supported across major Syncfusion® ASP.NET MVC Controls, including data visualization, data management, scheduling, editing, file management, and diagramming controls. For a complete list of supported components are listed below.

Component Assembly
Grid Syncfusion.AspNetMvc.Grid
Gantt Syncfusion.AspNetMvc.Gantt
Charts Syncfusion.AspNetMvc.Charts
FileManager Syncfusion.AspNetMvc.FileManager
Schedule Syncfusion.AspNetMvc.Schedule
RichTextEditor Syncfusion.AspNetMvc.RichTextEditor
BlockEditor Syncfusion.AspNetMvc.BlockEditor
Diagram Syncfusion.AspNetMvc.Diagram

Why we collect telemetry:

The collected telemetry helps us:

  • Understand feature adoption and usage trends.
  • Identify frequently used components and frameworks.
  • Prioritize future product investments and roadmap decisions.
  • Detect compatibility trends across .NET versions, operating systems, and development environments.

What information is collected?

Syncfusion collects only a limited set of anonymous usage data during development to understand product usage and improve product planning. No personal information or user-generated content is collected.

The following information may be collected:

  • Component Name : The Syncfusion component being used (for example, DataGrid, TreeGrid or Chart). Used to understand component usage and adoption.
  • Assembly Name : The Syncfusion assembly or package in use (for example, Syncfusion.AspNetMvc.Grid). Used for product diagnostics.
  • SDK Name : The Syncfusion SDK being used (for example, Chart SDK). Used to understand SDK adoption.
  • SDK Version : The SDK version shipped with the product. Used for release planning and compatibility analysis.
  • Framework : The target development framework (for example, .NET). Used to understand framework adoption.
  • Framework Version : The version of the target framework (for example, .NET 8). Helps prioritize framework support.
  • Operating System : The operating system used during development (for example, Windows, Linux, or macOS). Used for platform compatibility analysis.
  • Machine Architecture : Processor architecture (for example, x64, x86, or ARM64). Used to understand hardware trends.
  • Session ID (Hashed) : A randomly generated identifier representing a single development session. Used to group telemetry events within the same session.
  • Event Name : Product events (for example, component_initialized or feature_name). Used to understand component and feature usage trends.

NOTE

No user-generated content (e.g., code, files, or personal data) is collected.

What information is Not collected?

Syncfusion does not collect:

  • Personal information (name, email address, customer ID, company information)
  • Source code
  • Documents or files
  • Application data
  • User-generated content
  • Business data
  • Prompts or AI conversations
  • Authentication credentials
  • License keys
  • Any information that can directly identify an individual
How to disable telemetry (Opt-out)

Telemetry can be disabled at any time by calling Telemetry.Disable() during the application startup process, before using any Syncfusion features in your ASP.NET MVC application.

using Syncfusion.Telemetry; 

// Disable Syncfusion telemetry. 
Telemetry.Disable(); 

// Your Syncfusion code follows here.

Once disabled, Syncfusion applications continue to function normally. The only difference is that telemetry data will no longer be collected.

NOTE

Call Telemetry.Disable() before creating or using any Syncfusion features in your application.

Grid

Bug Fixes

  • #I858884 - Resolved a script error that occurred when scrolling after destroying a Grid with sticky header enabled.

TreeView

Features

  • #I839469 - Provided virtualization support for the TreeView component using the enableVirtualization API to efficiently render large datasets and improve performance.
